1. THE MAGNETIC FIELD

A magnetic field is manifested by a force affecting certain materials in its environment, acting on moving electrical charges. The magnitude of this force decreases as a function of the distance between the magnetic field emitter and its action point. Magnetization is a vector quantity which characterizes on a macroscopic scale the magnetic behaviour of a material sample. It is measured in amperes per metre (A/m) or in Tesla (T). (1)

Ferromagnetism designates the ability of certain material samples to become magnetised under the effect of an external magnetic field, and to retain part of this magnetisation. On a microscopic scale, a ferromagnetic material can be described as a set of independent magnetic domains (Weiss domains). When the magnetic moments of the domains are not aligned, the total magnetostatics energy of the material is minimised: the material is not magnetised. (2)

For demagnetization purposes, a damped magnetic excitation field is applied so that certain domains are reversed more than others, depending on the magnetic excitation force passing through them. This leads to a state of magnetic disorder equivalent to the state of a non-magnetized material. (3 and 4)

There are relatively intense magnetic fields all around us in daily life. It goes without saying that mechanical watches are influenced by them, and thereby undergo potentially significant operating variations, i.e. which affect the rate precision.

It should be noted that the Earth’s magnetic field varies between 25 and 65 μT, depending on geographic position. The most significant items in everyday life which can affect the rate of a mechanical watch by means of a magnetism effect are computers, mobile phones, TVs, refrigerators, etc. Magnetic flux measurements (taken at 10 cm from the source) have revealed values of 60 μT for an electric toothbrush, 75 μT for a mobile phone and 110 μT for a computer. Consider too that watchmaking tools often have a magnetic charge capable of disrupting the rate of a watch !

The distance at which a watch is placed from the magnetising object is an important factor. Although watch manufacturers regularly equip their cases with protective materials or opt for non-magnetic components, nevertheless rate problems due to magnetism remain very common.

2. DESCRIPTION

The HOROTEC© MAGTEST is an electronic device for the detection of magnetism in μTesla (μT), demagnetization and control of magnetic remanence of watches, movements, tools and watch parts. It combines the measurement function with the demagnetization function in a single device. After demagnetization, the residual magnetism value in μT can be checked again.

B. Demagnetization cycle.

3. HOW TO INTERPRET THE MAGNETIC FIELD WITH THIS DEVICE

Large metal parts, such as a movement, modify the lines of the earth’s magnetic field. For this reason, an indicative value of up to 50 μT can be considered without any influence or consequence on the functioning of the movement. For small parts, such as screws, the displayed values must be considered as real remanence values.

The search for magnetic remanence is active. If the displayed value is greater than «0 μT», it is recommended to reset the sensors. see paragraph 10D4

A2. Sensors

There are 5 sensors and one of them is located in the centre of the detection surface. The others are in the corners of a 1.5 cm square. They can measure the magnetism force as well as the position. A dot on the LCD screen shows a sensor with its position and the dot size is proportional to the magnetic force.

To check the degree of magnetism of small parts (screws for example), it is recommended to place them in the white areas of the example shown here. The sensor placed in the centre and the two zones between the 3 outer circles (in red) will not detect the degree of magnetism of the small parts.

Place the object to be tested on the DETECT ZONE surface.

<->

- If the screen remains neutral (as in the image above), it means that the object placed on the detection surface is not magnetized

- If red dots appear on the screen and a positive value in μT (as shown in the image below), it means that the object placed on the detection surface is magnetized.

In case of magnetic remanence, the value displayed in μT, is the difference between the value of the Earth’s magnetic field and the magnetism of the object being tested.

In addition to the value displayed in μT, red dots (up to 5) appear on the display indicating :

- By their presence, the magnetization surface

- By their size (diameter of the red dot more or less large), the importance of magnetism between the various sensors. The value displayed in μT, will always be the highest value detected by the 5 sensors.

DEMAG

Place the object on the DEMAG ZONE surface and press the key

to demagnetize the object.

If the screen displays the presence of magnetism without any object on the detection surface DETECT ZONE, it is recommended to reset the sensors.

+ see paragraph 10D4

Information : In automatic mode, the device switches directly from DETECT mode to DEMAG mode. Once the detection is complete (screen with red dots), remove the object from the DETECT ZONE surface. The device automatically switches to DEMAG mode. Place the object on the DEMAG ZONE surface and press the DEMAG button to start demagnetizing the object.
